Getting Started
2.1.
Xplained Pro Quick Start
Three steps to start exploring the Atmel Xplained Pro platform:
1. Download Atmel Studio.
2. Launch Atmel Studio.
3. Connect a USB cable (Standard-A to Micro-B or Micro-AB) between the PC and the DEBUG USB
port of the board.
When the Atmel SAME70-XPLD is connected to your computer for the first time, the operating system will
®
perform a driver software installation. The driver file supports both 32- and 64-bit versions of Microsoft
®
®
Windows XP, Windows Vista , Windows 7, and Windows 8.
Once the board is powered, Atmel Studio will auto detect which kind of MCU and extension board(s) are
connected. Atmel Studio will present links to relevant information like datasheets and kit documentation.
The kit landing page in Atmel Studio also has the option to launch Atmel Software Framework (ASF)
example applications for the kit. The SAM E70 device is programmed and debugged by the on-board
Embedded Debugger and therefore no external programmer or debugger tool is needed.

Xplained Pro
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The
platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated
with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data
streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards,
which are connected through a set of standardized headers and connectors. Each extension board has
an identification (ID) chip to uniquely identify which boards are connected to an Xplained Pro MCU board.
This information is used to present relevant user guides, application notes, datasheets, and example
code through Atmel Studio.
3.1.
Embedded Debugger
The SAME70-XPLD contains the Atmel Embedded Debugger (EDBG) for on-board debugging. The
EDBG is a composite USB device of three interfaces: a debugger, Virtual COM Port, and a Data Gateway
Interface (DGI).
Together with Atmel Studio, the EDBG can program and debug the ATSAME70Q21. On the SAME70XPLD, the SWD interface is connected between the EDBG and the ATSAME70Q21.
The Virtual COM Port is connected to a UART on the ATSAME70Q21 and provides an easy way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and
stop bit settings. Note that the settings on the ATSAME70Q21 must match the settings applied in the
terminal software.
Note: If not set automatically, data terminal ready (DTR) must be set in the terminal software.
The DGI consists of several physical interfaces for communication with the host computer.
Communication over the interfaces are bidirectional. It can be used to send events and values from the
ATSAME70Q21 or as a generic printf-style data channel. Traffic over the interfaces can be timestamped
on the EDBG for more accurate tracing of events. Note that timestamping imposes an overhead that
reduces maximal throughput. Atmel Data Visualizer is used to send and receive data through DGI.
For further documentation on the EDBG, see the EDBG User Guide.
3.2.
Hardware Identification System
™
All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and
sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information,
code examples, and links to relevant documents. The table below shows the data fields stored in the ID
chip with example content.

Power Sources
The SAME70-XPLD kit can be powered by several power sources listed in the table below.
Warning: The 3.3V power domain is locally generated and must never be supplied from
external sources or this would damage the on-board regulators.

In case of USB power sources, the board automatically detects and switches to the available one. If the
two are present (which is no problem whatsoever) the following priority applies:
1.
2.
Target USB (J302 connector)
Embedded Debugger USB (J900 connector)
Info: USB sources supposedly provide a maximum current of 500mA. Calculate the power
budget of your system, there is a possiblity this could be not enough if your SAME70-XPLD also
connects to power demanding extension boards.
The optional 5Vcc power source from the Arduino connector J501 is connected in parallel to the USB
power switching system, hence the following warning:
Warning: do not power the board form the Arduino shield (J501) when either of the two USB
sources are connected. Doing so could damage the board and potentially also damage the USB
port of your PC.
3.4.
Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100mil extension header. Xplained Pro MCU
boards have male headers, while Xplained Pro extensions have their female counterparts. Note that all
pins are not always connected. All connected pins follow the defined pin-out description in the table
below.

Shared Functionality
Arduino Connectors
Five 8-pin, one 10-pin, one 2×3-pin and one 2×18-pin headers footprints (J500 to J507) are implemented
on the board to enable the addition of "Arduino shields" extension cards. These accessory boards are
various and widely available on the market, often custom developed. Due to the PIO multiplexing of the
ATSAME70Q21, various peripheral signals may be connected to each pin. These connectors are
mechanically (location and footprint) compatible with the Arduino R3 shields.
Important: As the SAM E70 signals have a voltage level of 3.3V, 5V level shields cannot
properly function with SAME70-XPLD.
In addition to its standard IO functionality, the SAM E70 microcontroller can provide alternate functions to
external IO lines available on the J500 to J507 headers.
These alternate functions are:

Refer to the SAM E70 Series datasheet for further details on the PIO multiplexing and alternate function
selection.
Caution: Like the Arduino Due, SAME70-XPLD runs at 3.3V and the maximum voltage that
the I/O pins can tolerate is 3.3V, connecting higher voltages e.g. 5V to those I/O pin could
damage the board.
Important: not all pins of the shield connectors are necessarily connected to an I/O of the
ATSAME70Q21. Each shield should be checked for compatibility against the SAME70-XPLD
schematics before it is purchased and connected.

Current Measurement Header (VCC_MCU_P3V3 )
A 100mil pin-header marked "J203" is located at the upper edge of the SAME70-XPLD. All the power
going to the ATSAME70Q21 is routed through this header. To measure the power consumption of the
device, remove the jumper and replace it with an ammeter.
Figure 4-14 VCC_MCU_P3V3 Connector Placement J203
J203
Caution: Removing the jumper from the pin-header while the board is connected to otherwise
powered extension boards or systems may cause the ATSAME70Q21 to be powered through its
I/O pins. This could cause permanent damage to the device.
4.3.6.
VDDCORE Current Measurement
A 100mil pin-header marked "J201" is located at the upper edge of the SAME70-XPLD board. It is not
mounted by default and is replaced by a shunt trace between the two pads of the connector. All power to
VDDCORE of the ATSAME70Q21 is routed through this header. To measure the power consumption of
VDDCORE, cut the shunt trace between the two points, mount a header or solder wires and connect an
ammeter.

J201
Atmel SAME70-XPLD [USER GUIDE]
Atmel-44050A-SAME70-XPLD_User Guide-12/2015

Caution: Leaving J201 open while the main power source is present is to be avoided. This
would feed all power pins of the ATSAME70Q21 except VDDCORE, which may cause
permanent damage to the device.
4.3.7.
Chip Erase Header
The chip erase header J200 is connected to the SAM E70 erase pin (PB12) and the main 3.3V. To erase
the contents of the SAM E70 flash memory, set a jumper on J200 and turn the power supply on. The
jumper can be removed soon after the power is on (flash erasing takes only 200ms). Using the chip erase
jumper is the only way to erase a chip with the security bit set.

Clock Circuitry
The SAME70-XPLD board features three clock sources:
•
•
Two crystals for the ATSAME70Q21 processor
One crystal oscillator for the Ethernet MII/RMII chip
The crystals of the ATSAME70Q21 have cut-straps next to them that can be used to measure the
oscillator safety factor. This is done by cutting the strap and adding a resistor across the strap.
Information about oscillator allowance and safety factor can be found in the application note AVR4100;
information about clock calibration and compensation can be found in the application note AT03155.

Ethernet
The ATSAME70Q21 has a built-in 10/100 Mbps Ethernet IEEE 802.3 compatible MAC with RMII
interface. The SAME70-XPLD connects the MAC to a Micrel KSZ8081RNACA RMII physical-layer
transceiver (PHY), which is connected to one RJ45 Ethernet connector.
A unique EUI-48™ address is available on every SAME70-XPLD through the on-board AT24MAC402, the
EUI-48 address can be used as a MAC address for the KSZ8081RNACA. The address is also
programmed into the on-board EDBG.
Table 4-19 KSZ8081RNACA Connections on page 35 lists all pins connected from the SAM E70 to the
Ethernet PHY.
Info: Several of the Ethernet signals are shared with the trace connector and thus there is no
Ethernet support if trace is used in an application.

Embedded Debugger Implementation
SAME70-XPLD contains an Embedded Debugger (EDBG) that can be used to program and debug the
ATSAME70Q21 using Serial Wire Debug (SWD). The EDBG also includes:
•
•
•
•
a Virtual Com port interface over UART
an Atmel Data Gateway Interface over SPI
an I2C channel
connections to four of the SAM E70 GPIOs
Atmel Studio can be used as a front end for the Embedded Debugger.
